I used to buy 12 newspapers every day when I was a journalist. I'd be all covered in ink by the end of the day. Once I started getting information online it was immediately obvious to me what was going to happen to all those papers.

The transition was less immediately obvious with books. It's harder to read long form online. The Kindle and the Nook have done a really good job, but it took a long time.
